Backplane Lenovo ThinkSystem ST650 V2 2.5 inch SAS/SATA 8-bay

The Backplane Lenovo ThinkSystem ST650 V2 2.5" SAS/SATA 8-bay is a replacement drive backplane designed for use in the Lenovo ThinkSystem ST650 V2 server chassis. It supports eight 2.5-inch SAS or SATA hot-swap drives and provides the physical connectors and signal routing required for drive communication and tray-level serviceability in a rack server environment. This component restores or expands front-bay drive connectivity without requiring changes to the server motherboard or cabling layout when installed in compatible chassis.

Advantages

This backplane offers mixed SAS and SATA drive compatibility, enabling flexible use of different drive types within the same 8-bay front panel. Its hot-swap support permits drive replacement or addition without powering down the server, reducing service windows. The unit is engineered for direct fit into the ST650 V2 chassis to preserve alignment and secure mounting of drive carriers, maintaining system airflow and mechanical stability.

Suitable for

• Data center servers requiring front-bay drive replacement or upgrade
• Virtualization hosts needing increased or reliable local storage
• Storage expansion where an 8-bay 2.5" SAS/SATA interface is required
• Maintenance and repair tasks to restore drive connectivity in ST650 V2 systems

Key specifications

• Drive bays: 8 × 2.5-inch drive slots
• Supported interfaces: SAS and SATA host drive interfaces
• Drive access: hot-swap capable trays
• Form factor: front-panel backplane compatible with Lenovo ThinkSystem ST650 V2 chassis
• Connectivity: internal drive connector sockets and backplane-to-controller signal routing
• Mounting: designed for direct replacement installation in the specified chassis

How to use

To replace or install the backplane, power down the server and follow the ST650 V2 chassis disassembly instructions to access the front drive area. Remove the existing backplane by disconnecting all internal signal and power cables and unfastening retaining hardware, then install the replacement unit and reconnect cables ensuring secure seating of connectors. After reassembly, power on the server and verify drive recognition in the system management interface and operating system. For hot-swap operations, insert or remove drives using supported drive carriers while the server is online and observe operating system and storage controller LED indicators for proper device status.

Recommendations

Use the backplane with compatible Lenovo ThinkSystem ST650 V2 chassis and follow Lenovo service documentation for handling, static protection, and torque specifications. Confirm controller and firmware support for mixed SAS/SATA configurations and perform a full backup before performing drive replacement or array reconfiguration.
